DEVICE FOR OPERATING YARN-SEPARATORS IN SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 432,201, dated July 15, 1890.

Application filed August 26, 1889. Serial No. 321,927. (No model.)

To all whom it may concern.-

Be it known that we, JOHN JUDGE and JOHN SULLIVAN, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Devices for Operating Yarn-Separators in Spinning-Machines, of which the following is a specification.

Our invention relates to yarn-separators, so called, for rin g-spinning machines, the separators consisting of devices which extend between the spindles and prevent the yarn on adjacent spindles, in the spinning operation, from coming in contact one with the other.

Our invention consists of improvements in means for operating What are commonly known as Doyle Separators, or such separators as consist of thin blades vertically arranged between the spindles and having a pivoted or rocking support, all as is hereinafter particularly described and claimed.

The invention will first be fully described, in order that those skilled in the art may understand its nature and a way or ways in which it may be constructed and used, and will subsequently be specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, and to the letters of reference marked on the same, forming a part of this specification.

In the annexed drawings, Figure 1 is an end view of a separator, ring-rail, spindle, and their immediately-associated parts, showing said devices as heretofore arranged or associated and operated, the ring-rail being represented as lowered. Fig. 2 is a view similar to Fig. 1, the ring-rail being represented as raised. Fig. 3 is a view of the parts shown in Fig. 1 with ourimprovements applied thereto, the ring-rail being represented as lowered. Fig. 4 is a View of the same parts shown in Fig. 3, the ring-rail and separator-lifter being represented as in raised position. a detail hereinafter referred to. Fig. 5 is a rear view of the separator-lifter detached.

In the drawings, a designates the spindles; h, the spindle-rail, or rail upon which the spindles are stepped and by which they are supported. c is the ring-rail, and d is the lifting rod for raising and lowering the ring-rail in the operation of spinnin Fig. 4. is

The separators e consist of comparatively thin blades or tongues extending between the spindles and so constructed and arranged that they will prevent the yarn of one spindle from coming in contact with or striking and breaking down the yarn of an adjacent spindle. The separators e are secured at their rear ends upon a rock-shaft f, and are provided with rearwardly-projecting rods or stems g, upon which are arranged adjustable counterbalancing weights h, as shown, the arrangement being such, however, that a slight preponderance of the weight will be in the separators, so that the latter may be lowered by their own gravity when permitted so to move.

Prior to our invention separator-blades such as are shown in the drawings have been permitted to come in contact with the ring-rail, so that when the latter is raised it will also raise the separators. In Fig. 1 we have shown this old construction, (which is the kind or class of devices upon which our improvements have been wrought,) the ring-rail being represented as lowered. In Fig. 2 the same organization is shown; but the ring-rail is represented as having been raised and as having raised the separators. A number of objections attach to this organization and arrangement of parts, among which is the fact that there is liability of the separators acting to move the rings out of concentricity with respect to the spindles. Again, the ring-rail does not move the separators out of the way as soon as is usually 1'equired-as, for example, when it is desired to gain access to the spindles for the piecing of threads or in doffing the bobbins, brushing the rings, 850. These and other objections are overcome by our improvements, which consist of a rod 2', secured to the end of the stud j, which supports the lifting-rod d. The rod t is arranged in the rear of the ring-rail c, and extends up to a point a little above the latter, the said rod '5 moving in unison with the lifting-rod d and being guidedin its movements by a bracket .70, secured to a suitable stationary part of the frame, which bracket It is provided with an aperture Z, through which the rod t passes. (See particularly Fig. P.) The rod tis provided on its upper end with a vertically-adjustable strip or blade m, arranged to come in contact with the lower edge of the separator-blade 6 when the ring-rail is raised, and so raise the said separator-blade out of place between the spindles. The ad justable feature of the strip on is for the purpose of enabling it to raise the separators sooner or later, as the circumstances of the case may require. This adjustment of strip or blade m may be effected by means of the slot m formed in the lower end of the latter, and the fastening means, as a screw or screw and nut W19 arranged in said slot, as is clearly shown in Fig. 5, or in any other known manner. WVith these improvements, which are capable of attachmentto substantially allring-spinningframes, the separators (which are only of material use when the rail is at the bottom of its traverse) can be moved out of place between the spindles at the desired time, and all damage to the rings and other parts'of the machine is avoided.

Having thus explained the nature of our invention, and particularly described one of the ways of forming and using the same, we declare that what we claim is- 1. The spindles and their support, the ringrail and means for reciprocating it, combined with the vertically-movable rod 2', arranged said separators, all as hereinbefore set forth.

2. The spindles and their support, the ringrail, the lifting-rod d, and the rod 11, provided with the vertically-adjustable strip m, the rod 2 being connected with the lifting-rod to move in unison with it, combined with the rock-rod f, provided with the separator-blades e, the said blades being adapted to be engaged by the strip m, all'as hereinbefore set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 22d day of August, A. D. 1889.
